Transcatheter aortic valve implantation (TAVI)

TAVI is usually performed under light sedation with local anaesthetic, meaning you'll be slightly drowsy and pain-free throughout the procedure. Your consultant will insert a thin, flexible tube (a delivery catheter) through a small cut in the skin, usually in your groin but sometimes between your ribs or under your collarbone.

The catheter is then passed towards the heart and through the opening of the narrowed aortic valve. A small balloon may be inflated to open your aortic valve and make room for the artificial valve. Most artificial valves are made using bovine (cow) tissue. This new valve is expanded to fit in place of the old, narrowed valve. The whole procedure takes one to two hours.

Like all procedures, there may be some risks and side effects involved. Your consultant will explain these to you and let you know how to prepare. If you're having general anaesthetic or sedation, your consultant will tell you how long you should avoid eating and drinking for.

The recovery time for TAVI is generally much faster than for traditional open heart surgery. You'll be cared for in hospital for as long as your recovery requires, but most patients go home within two days following the procedure. You can expect some discomfort and will be given pain relief medication.

It may take up to four weeks to fully recover, but your consultant will let you know when you can get back to your usual routine, including work.
